One ate  1/3,  Another ate = 1/4.
Total ate =  1/3 + 1/4  = (4 + 3) / 12 = 7/12
Fraction the third girl got =  (The whole =1)  minus 7/12
=  1 - 7/12 =  (12 - 7) / 12 = 5/12
The third girl ate 5/12 of the pizza.
        
             
        
        
        
Responder:
x = 42,4
Explicación paso a paso:
Podemos encontrar el valor de x ya que no se nos dice qué buscar
La suma de dos ángulos suplementarios es 180 grados, por lo tanto;
2x - 14 + 3x - 18 = 180
2x + 3x - 32 = 180
5 veces = 180 + 32
5 veces = 212
x = 212/5
x = 42,4
Por tanto, el valor de x es 42,4
